Horizontal Scan Rate - Example

Example

  • Display Mode at 1280x1024 @ 60Hz means it draws 1024 lines x 60 per second
  • Taking Vertical blanking interval into account, it would actually draw 1024x1.05 lines for a full frame cycle
  • Therefore, it draws 1024x1.05x60 lines per second = 1 line per 1/(1024x1.05x60) second
  • Horizontal scan rate: 1/(1024x1.05x60) sec ~= 1.55009921E-5 sec or 64.512 kHz

Famous quotes containing the word example:

    “Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
    —Marcel Proust (1871–1922)
